Half Adder

Half Adder

A half adder adds two single bits and produces two outputs:

• Sum (S): the XOR of the inputs — the result bit
• Carry (C): the AND of the inputs — the carry to the next bit position

When 1 + 1 = 2 in binary is 10: sum bit is 0, carry bit is 1.

The half adder is called "half" because it cannot handle a carry-in from a previous addition — for that, you need a full adder.

Circuit

S = A XOR B
C = A AND B

Your Task

Implement halfAdder(a, b) that returns an object { sum, carry }.

Then print the result of adding 1+1 and 1+0.
